Question 1:
A car's speed changes from 10 m/s to 55 m/s in 4 seconds. Calculate the acceleration of the car in units of meters per second squared.
Neglecting air resistance, what is the speed of an object (in m/s) 1.2 seconds after being dropped from a great height?
Starting from rest, a 2 kg object acquires a speed of 31 m/s in 2 seconds. Calculate the net force (in Newtons) acting on the object.
If an object's speed is increased to 5 times its original speed, the object's kinetic energy will increase to what number times its original kinetic energy?
A 600 N person runs up a flight of stairs in 10 seconds. How much power (in watts) was needed to run up the stairs if the vertical height of the stairs is 23 meters?
A ball is thrown straight upward with an initial speed of 27 m/s. Assuming no air resistance, how much time (in seconds) will it take for the ball to reach its maximum height?
Neglecting air resistance, what is the speed (in m/s) of an object just before striking the ground if it was dropped at rest and fell for 1.5 seconds?
